IMPROVEMENT IN HARROWS.

To all whom yit may concern:

Be it known that I, ANDREW J. B. FOSTER, of Mount Pleasant, in thecounty of Maury and State of Tennessee, have invented certain new anduseful Improvement-s in Harrow; and

I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying draw'- ing,and to the letters of reference' marked thereon, which form part of thisspecification.

The nature of my invention consists in the construction and arrangementof a harrow, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a bottom View of my harrow. Fig. 2 is a longitudinal sectionof the saine.

A A represent the. two side pieces of my harrow, made of any suitabledimensions. Between these side pieces are three sets 0f rollers, B B,one set in the center and one near each end. These rollers are placedupon rods au fastened in the side pieces. Each set of rollers may beformed of any number desired, and the rollers should be separated bymeans of'washers, as shown.

In the two spaces between the three sets of rollers are cross-bars C C,placed in the side pieces, two in each space at a suitable distanceapart.4 In each set of these cross-bars are attached longitudinal ubarsD by bolts, and t0 each of these bars is fastened a tooth, G. Be-

tween the bars D in the under sides of the land are made of iron ofsuitable thickness.

.In a full-sized harrow they are to be placed about six inches apart,crosswise, and so situated as to cause the teeth in the rear to cutbetween the front teeth.

The rods a, that carry the rollers B and the cross-bars G are alladjustable in the side pieces A A, b'y means of holes therein, for thepurpose of regulating the depth at which the teeth are to work.

Scrapers may also be attached in the side pieces for keeping the rollersclean, if needed.

Having thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent, is-

l. In a barrow, the combination of the adjustable cross-bars G C, thebars D D, cony necting the same, and the half-moon-shaped barrow-teethGr, secured to the bars' D, substantially as herein set l'orth.

I 2. The combination of the side pieces A A, the three sets of rollers Bplaced upon adjustable rods a, the adjustable cross-bars C.connecting-bars D, and teeth G, all constructed substantially as and forthe purposes herein set forth.
